APPARATUS FOR STEREOTYPING.

SPECIFICATION forming part of Letters Patent No. 436,372, datedSeptember 16, 1890.

Application filed May 3, 1890.

To all whom it may concern:

Be it known that 1, CHARLES T. MURRAY, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements in Apparatusfor Stereotyping, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to an improvement in an apparatus for stereotyping;and it consists in the novel construction, combination, and arrangementof the several elements hereinafter set forth, and pointed out in theclaims.

In the drawings, Figure 1 is a sectional elevation of a machineembodying my invention, the section being taken longitudinally thereof;and Fig. 2 is a detail view of a damper made use of in constructing themachine.

The object of my invention is to combine, in very compact form, amelting-pot, a furnace, and a combined steam-boiler and drying-platenand yoke and screw therefor and all proper attachments for each of theseparts, whereby steam may be generated direct within said platen orsteam-table, obviating the necessity of a separate steam-boiler, as willnow be described.

A represents the improved-machine as a Whole, the same being providedwith a suitable furnace B and proper attachments, with a melting-pot Cmounted over said furnace in or upon the framing of the machine andgrate-bars D orother fuel-supportin g devices.

The combined steam-boiler or steam-table E is supported in the rear ofthe melting-pot; or, if desired, I may dispense with said melting-pot inthis machine and then locate the boiler and steam-table directly overthe firebox of the furnace. Said boiler and table E is supplied with theusual upperplaten and yoke F. screw H, and hand Wheel or lever I foroperating said upper platen in the usual manner, and said boiler isfitted with all necessary means for supplying it with water such, forinstance, as a removable bucket or other vessel J 5 or, if desired,Water may be supplied direct from the water-pipes of the building andthrough a proper series of pipes and rubber hose-such as K, L, M, N, andO- with which is connected a suitable handpump P, fitted with ahand-lever Q, which latter operates the piston of said pump. The

Serial No. 350,437, (No model.)

upper end of the pump piston-rod is attached to said hand-lever, and theinner end of the hand-lever is fulcrumed to a vertical rod pivoted tothe framing of the machine. R is a suitable glass water-gage or othermeans for showing the height of Water in said boiler, and the lower endof the water column carrying said glass gage is connected to the pipes MN for the purpose mentioned. The combined boiler and drying-platen isalso provided with a safety-valve S for escape of surplus steamgenerated during use and connecting-pipe T. A steam-gage U is alseprovided for the usual purpose and connected to the boiler by pipe V.

The yoke F is located longitudinally with respect to the machinedirectly above the combined steam boiler and steam-platen, whereby theinsertion of stereotype-plates beneath the upper platen is permittedfrom either side of the machine. The machine is also provided with afine or pipe W, leading from the forward end of the boiler to thesmoke-pipe Y at the rear or side, and with a second flue or outlet X,opening into said smoke-pipe at the rear of the boiler, and a suitabledamper'plate Y is fitted over the mouth of said pipe W, and has its edgecut out to the contour of the under surface of said boiler, so as to fitthereon snugly when the damper-plate is turned upward, as indicated bydotted lines, and so cut off the pas sage of heat rearward under.theboiler, permitting same to pass down and out through said pipe Wwithoutimparting heat to the boiler, and vice versa. When said damper isdown, the pipe WV is closed thereby, causing the products of combustionto pass under the boiler and out to smoke-pipe by way of X. The normalposition of said damper is closing the pipe WV, and when the pressure ofsteam in boiler E rises too high said damper should be raised to preventfurther heating of said boiler.

Having thus described my invention, what I claim is 1. In a stereotypingapparatus, a casing, a hollow drying-platen constituting a boilerlocated therein, a fire-box, a smoke-flue, and a water-supply pipeconnecting with said hollow platen, substantially as described.

2. In a stereotyping apparatus, the combination of a drying-platen andsteam-generator, a furnace having a suitable frame, a meltingpot, andoperating attachments, all mounted in or upon the integral frame of thefurnace, substantially as set forth.

3. In a stereotyping apparatus, a furnacechamber, a melting-pot, and ahollow dryingplaten located therein, a pipe W, connecting with theforward end of the furnace-chamber 1c and leading to the smoke-flue,apipe X, leading from the rear end of the furnace-chamber, and a damperY, for cutting oif the draft through either of said pipes W or X, asdesired, substantially as set forth.

In testimony whereof I affix my signature in 1 5 presence of twowitnesses.
